Trains That Passed in the Night

Winston Link was a young practitioner of an old photographic tradition, one still much used, but which now commands little public notice. He developed a strong personal style within the technique of using cameras that were usually fixed in place, mounted on heavy tripods and using large negatives, typically 4 x 5 inches in size. The dynamic qualities of photographs made this way came through their careful planning: the precise placement of the camera, and equally careful placement of the lighting sources, with people and objects also being arranged with an eye for the final effect. Photographs using this technique were (and still are) made by the millions for advertising and illustrative purposes. While this manner of photography is still widely used, we have come more often to think of photographic truth through another aesthetic, one created by photographers using small hand held cameras. Sometimes described by the generic term street photography, photographers who work in this way usually move rapidly and invisibly through their surroundings, making images using only the light available and leaving the environment untouched and unchanged. Not only did Winston Link use a different photographic technique, his motivations were different from street photographers. His interest, in all his work, was to create as precise and careful a record as possible of the scene being photographed. Using lessons he learned from his commercial advertising photography, Link had less interest in documenting life as he found it than in creating images of life as he (or his clients) might wish it to be. Thus in his railroad photos, Link built a record that not only documented the locomotives and trains themselves, but emphasized the benefits of the railroad to the life of the communities through which it passed. He was, in his way, preparing and executing an advertising campaign for the American Steam Railroad, and the good life in the United States which it supported. In many of his photographs, the passing train is incidental to the activity in the foreground, be it buying groceries, taking a swim or herding cows. Yet, even in the background, the steam railroad was still the essential element which stitched together Winston Link\u27s personal vision of this good life in America

The Impact of Visual Style on User Experience in Games

The visual style in a game is an aspect of user experience that is often neglected in user experience studies in games. Visual style is often reflective of the tone that a game designer intends to convey or the assumption of what the intended audience would prefer, and it is an important aspect of how a player experiences a game. This thesis investigated how visual style impacts user experience, by observing user experience from two different approaches, moment and memory-based experiences (engagement and enjoyment), through the manipulation of style in a game. The manipulated aspects of visual style were color and form. While the impact of color and form on experience is inconclusive, visual preference by a player does appear to be indicative of whether or not a player will be engaged and enjoy an experience. In order to properly control any unknown variables, the demo being used for this study was made by the researcher, providing the flexibility to manipulate the style as necessary

The Niemann-Pick C1 and caveolin-1 proteins interact to modulate efflux of low density lipoprotein-derived cholesterol from late endocytic compartments

The Niemann-Pick C1 (NPC1) protein has a central role in regulating the efflux of lipoprotein-derived cholesterol from late endosomes/lysosomes and transport to other cellular compartments. Since the NPC1 protein has been shown to regulate the transport of cholesterol to cellular compartments enriched with the ubiquitous cholesterol-binding and transport protein caveolin-1, the present study was performed to determine whether the NPC1 and caveolin-1 proteins interact and function to modulate efflux of low density lipoprotein (LDL)-derived cholesterol from endocytic compartments. To perform these studies, normal human fibroblasts were grown in media with lipoprotein-deficient serum (LPDS) or media with LPDS supplemented with purified human LDL. The results indicated reciprocal co-immunoprecipitation and partial co-localization of the NPC1 and caveolin-1 proteins that was decreased when fibroblasts were grown in media with LDL. Consistent with interaction of the NPC1 and caveolin-1 proteins, a highly conserved caveolin-binding motif was identified within a cytoplasmic loop located adjacent to the sterol-sensing domain (SSD) of the NPC1 protein. To examine the functional relevance of this interaction, fibroblasts were transfected with caveolin-1 siRNA and found to accumulate increased amounts of LDL-derived cholesterol within late endosomes/lysosomes. Together, this report presents novel results demonstrating that the NPC1 and caveolin-1 proteins interact to modulate efflux of LDL-derived cholesterol from late endocytic compartments

Evaluating Novel Methods of Classifying Interlimb Asymmetries Within Collegiate American Football Players

International Journal of Exercise Science 15(6): 473-487, 2022. Over the last few years, researchers and sport scientists have expressed an increased interest in the effects of interlimb asymmetry on aspects of sport performance such as jumping, sprinting, and changing direction. This study aimed to evaluate the diagnostic utility of three different means of classifying asymmetry to highlight if a 6-week resistance training intervention can meaningfully reduce levels of asymmetry, and to determine the relation between asymmetry reduction and improvements in change of direction (CoD) performance, if any. Eighteen, division-two collegiate American football skill position players completed all pre- and post-intervention procedures. These procedures involved the completion of the Bulgarian Split Squat (BSS) exercise from which asymmetries in relative average power (Rel.AP), and relative peak power (Rel.PP) were derived. Additionally, participants completed three repetitions within the 505 and L-drill tests to quantify CoD performance. Results from our study show that participants classified as asymmetrical, exhibiting observed asymmetry in Rel.PP scores larger than the sample mean plus one standard deviation, had the greatest likelihood of reducing asymmetry (OR = 6.99, 95% CI: 1.4, 12.5) and improving L-drill performance (OR = 1.33, 95% CI: -2.1, 4.8). Further, our training intervention meaningfully reduced Rel.AP asymmetry (p = 0.027, Cohen’s d = 0.73). At the group level, these reductions in asymmetry were accompanied by improvements in L-drill performance that were larger than the sample smallest worthwhile change (SWC). At the individual level, however, change scores in asymmetry and change scores in CoD performance only showed small, non-significant correlations

Ku Band transmitarray lens for microwave applications

In this document a microstrip constrained lens device for Ku band, for microwave purpose, is presented. This paper offers an overview of artificial lens-type devices and the proposed transmitarray lens is thoroughly studied in terms of design and manufacturing, with architecture discussion and selection, along with the design, manufacturing and validation of all the forming components of the transmitarray (transmission circuits, radiating elements, etc.). Each element is properly characterized and assembled properly in the complete transmitarray prototype. Eventually, radiation pattern measurements as well as gain and directivity values, are provided to show the proper behaviour of the proposed transmitarray lens
